Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
hanh trinh » canh tranh, hanh chinh
doi chieu » doc hieu, doi chi, ho chieu
dan thanh » dang thanh, danh thanh, ban thanh
thanh lap » thanh san, phan lap, thanh hai
van dung » van dong, xay dung
cong dan » cong san, cong tan, huong dan
ap dung » xay dung

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: doi chieu xanh - hanh trinh ((ap dung) OR (((van dung) OR (tin dung)))) cong dan thanh lap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi chieu xanh - hanh trinh ((ap dung) or (((van dung) OR (tin dung)))) cong dan thanh lap~".
• Adding a wildcard symbol may retrieve word variants: doi chieu xanh - hanh trinh ((ap dung) or (((van dung) OR (tin dung)))) cong dan thanh lap*.
